-x^2-y^2+4x=0

Lösung

- x^{2} - y^{2} + 4 x = 0

Lösung

(a, b) = (2, 0), r = 2

Schritte zur Lösung

- x^{2} - y^{2} + 4 x = 0

Rewrite

- x^{2} - y^{2} + 4 x = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - 0)^{2} = 2^{2}

Therefore the circle properties are:

(a, b) = (2, 0), r = 2

16x^2+16y^2+98x-40y=315

16 x^{2} + 16 y^{2} + 98 x - 40 y = 315

x^2+y^2-x+2y-30=0

x^{2} + y^{2} - x + 2 y - 30 = 0

(x-6)(x-6)+(y-7)(y-7)=64

(x - 6) (x - 6) + (y - 7) (y - 7) = 64

36 = x^{2} + 12 + y^{2}

3 x^{2} + 6 x + 3 y^{2} = 0
